Nitrostarch is a secondary explosive [1] similar to nitrocellulose. Much like starch, it is made up of two components, nitrated amylose and nitrated amylopectin. Nitrated amylopectin generally has a greater solubility than amylose; however, it is less stable than nitrated amylose. [2]
The solubility, detonation velocity, and impact sensitivity depend heavily on the level of nitration. [2]
Nitrostarch is made by dissolving starch in red fuming nitric acid. It is then precipitated by adding the solution to concentrated sulfuric acid. [2]
Nitrostarch can be stabilized by refluxing it in ethanol to drive off the left over nitric acid. [2]
Nitrostarch was first discovered by French chemist and pharmacist Henri Braconnot. [3]
In World War I, it was used as a filler in hand grenades. [4]
